Re: Poor gas mileage

I bought a brand new 2009 Civic EX early in September. I have been taking gas mileage readings every time I fill the tank and get an average 24-25mpg. I tend to drive 75mph on the highway and 5mph over the posted speed limits. Also the area around me is very hilly.

Highway mpg is rated at 65mph I believe.

Long distance cruising at constant speeds (even 60-70MPH) and the tank will seem like's it 20 gallons- not 13.

Drive like me ( I do like the sound of the engine !) and it can be unimpressive for a 1.8. (Seems like my old 3.8 Ford).
Also the tires can make a noticble difference, which I thought was just BS in the tire sales brochures.
Thats exactly what I was thinking, was the original OP keeping up on tire pressure as well? From my understanding, cold weather causes the tire pressure to drop, and if the OP isnt keeping up with it, it could cause the MPG's to drop considerably. Low tire pressure = bad MPG's

Just my 2 cents, fuel for thought
